Wheel-like bricks and minimal matching covered graphs
A connected graph G with at least two vertices is matching covered if each of its edges lies in a perfect matching. We say that an edge e in a matching covered graph G is removable if G-e is matching covered. A pair {e; f} of edges of a matching covered graph G is a removable doubleton if G-e-f is matching covered, but neither G-e nor G-f is. Removable edges and removable doubletons are called removable classes, introduced by Lovasz and Plummer in connection with ear decompositions of matching …

New #WhiteHouse edict targets jurisdictions that are perceived to not be removiving "Endemic #vagrancy" and "drug users" with punitive measures. Specifically mentioned are threats to cut federal funding to cities that do not stop allowing so-called “harm reduction” or “safe consumption” sites for…

History’s booming in podcasts – but many of its academics are out of a job
We live in momentous times, with history podcasts and books more popular than ever. So why is the academic discipline in crisis?

Semiregular and strongly irregular boundary points for nonlocal Dirichlet problems
In this paper we study nonlocal nonlinear equations of fractional $(s,p)$-Laplacian type on $\mathbf{R}^n$. We show that the irregular boundary points for the Dirichlet problem can be divided into two disjoint classes: semiregular and strongly irregular boundary points, with very different behaviour. Two fundamental tools needed to show this are the Kellogg property (from our previous paper) and a new removability result for solutions in the $V^{s,p}$ Sobolev type space, which we deduce more ge…

Esto del acuerdo EU - EEUU de 15% aranceles a EU (nada a EEUU?), acuerdo de gastar miles de millones en petroleo, gas y armas de EEUU; me parece un muy mal acuerdo del que Europa es la única que cede para gastar mšs en cosas que deberíamos dejar de gastar para consumir interno en renovables y defensa soberana. Y lo vende como un logro Von Der Leyen...

I doubt these are the last 3 Tandon Data PACs in captivity but they may be.
I'm considering dismantling them and driving a spike through the drives.
For anyone wondering, they were removable drives that had 30Mb and 40Mb capacities. There was no controller electronics that was a separate board on the PC. And we had dual bay small tower PCs as well.
The original customer was Xerox.
Essentially they ate up remanufactured drives which otherwise had become difficult…

Kalb-Ramond Black Holes Sourced by ModMax Electrodynamics: Some Perturbative Properties in the Phantom Sector
We formulate and analyze a new class of electrically charged black hole (BH) solutions in Lorentz-violating gravity, where nonlinear ModMax electrodynamics is nonminimally coupled to a Kalb-Ramond (KR) two-form field. The spontaneous breaking of local Lorentz symmetry is triggered by a nonzero vacuum expectation value of the KR field, characterized by a small dimensionless parameter $\ell$. To incorporate both standard and phantom sectors, we introduce a discrete sign-flip parameter $ζ= \pm1$,…
